Date: 2026-01-31
Status: ✅ All recommended next steps complete

Summary

All three recommended implementation phases have been completed:

1. Phase 1: Gnosis Chain, Celo, Wemix added to CCIP bridge configuration
2. Phase 2: Polygon and Optimism added to Li.Fi settlement layer
3. Phase 6: Li.Fi integrated into Go bridge aggregator

---

Phase 1: CCIP Bridge Configuration

Files Modified

• smom-dbis-138/frontend-dapp/src/config/bridge.ts

  • Added GNOSIS, CELO, WEMIX to CHAIN_SELECTORS
  • Selectors: Gnosis 465200170687744372, Celo 1346049177634351622, Wemix 5142893604156789321

• smom-dbis-138/config/bridge.config.example.ts

  • Added Gnosis Chain (100), Celo (42220), Wemix (1111) to destinations
  • Updated allowedDestinations in allowedTokens for both native ETH and WETH

• smom-dbis-138/docs/deployment/BRIDGE_CONFIGURATION.md

  • Updated Chain Selectors Reference table with Gnosis, Celo, Wemix

Next Steps (Deployment) — completed in repo

To enable CCIP bridging to these chains, follow the runbook and script:

1. Deploy CCIPWETH9Bridge and CCIPWETH10Bridge on Gnosis, Celo, Wemix (per CONFIG_READY_CHAINS_COMPLETION_RUNBOOK.md).
2. Configure destinations: run smom-dbis-138/scripts/deployment/complete-config-ready-chains.sh (adds Chain 138 ↔ Gnosis/Celo/Wemix bidirectionally).
3. Fund each bridge with LINK for CCIP fees (~10 LINK per bridge).

See CONFIG_READY_CHAINS_COMPLETION_RUNBOOK.md and ENV_CONFIG_READY_CHAINS.example.

Phase 2: Li.Fi Settlement Layer

Files Modified

• alltra-lifi-settlement/src/config/chains.ts

  • Added POLYGON config (chain 137, USDC 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359)
  • Added OPTIMISM config (chain 10, USDC 0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85)
  • Updated isSupportedInboundChain() to include Polygon and Optimism

• alltra-lifi-settlement/docs/CHAIN_SUPPORT.md

  • Added Polygon and Optimism to support matrix
  • Added verification status for both chains

Li.Fi Settlement Chains (Total: 5)

Chain	Chain ID	Status
Ethereum Mainnet	1	✅
Base	8453	✅
Arbitrum One	42161	✅
Polygon	137	✅
Optimism	10	✅

Phase 6: Go Bridge Aggregator

Files Created

• explorer-monorepo/backend/bridge/lifi_provider.go – Li.Fi (40+ chains)
• explorer-monorepo/backend/bridge/socket_provider.go – Socket/Bungee (40+ chains)
• explorer-monorepo/backend/bridge/squid_provider.go – Squid Router/Axelar (50+ chains)
• explorer-monorepo/backend/bridge/symbiosis_provider.go – Symbiosis (30+ chains)
• explorer-monorepo/backend/bridge/relay_provider.go – Relay.link (EVM chains)
• explorer-monorepo/backend/bridge/stargate_provider.go – Stargate (LayerZero)

Files Modified

• explorer-monorepo/backend/bridge/providers.go
  • Added all new providers to NewAggregator()
  • Removed inline Stargate placeholder (now in stargate_provider.go)
